Long shots of the base show The jungle right up to the edge of the camp, however in Vietnam all Australian army bases had the trees and shrubs cleared sometimes up to two kilometres all around to eliminate any cover for an attack on the base.

When notice of their leave is posted, the PA mentions Newcombe and Orantes. These are two tennis players: John Newcombe of Australia and Manuel Orantes of Spain. Newcombe and Orantes only played each other once - in 1973 (which was after the Australians had withdrawn from Vietnam and long after the SAS had withdrawn - October 1971). During their careers, Newcombe won 7 grand slams, whilst Orantes won one.

Just before the last skirmish scene Bill and Harry observe what is supposed to be a convoy of helicopters en-route to battle. However it's quite obvious that there are really only two Huey's and one Chinook. Some slicker editing or directing could easily turn those three helicopters into a convoy resembling as many helicopters as the director required.

During the contact on the bridge scene, white painted lane lines are shown on the road, something not seen in rural Vietnam but present in Australia.

In the final scene of the film, when Harry and Bill have flown home to Australia they sit in a bar and have a beer. Through the window the Sydney skyline can clearly be seen in the distance. However, the Australian SAS are based in Perth, not Sydney and it would have been to Perth that they would have been flown home to.

During the first skirmish when Scott gets shot, the lieutenant shouts for the 203 (grenade launcher), someone answers that Mick has it and Mick is behind him. However Bill in the forward position doing the firing clearly has the 203 attached to his rifle.
